PHP loop syntax issues - php

Question

I need to add a counter to the loop as well as pulling contents. What is the syntax for adding the "and for ($ColCount = ColCount + 1)"
<?php $ColCount = 0?>
<!--get artwork thumbnails -->
<?php
$dbname = 'pdartist2';
$table = 'artwork';
// query
$result = mysql_query("SELECT AID, ThumbFilePath, Title, DisplayOrder FROM artwork where SCID = '$SCID' ") or die(mysql_error());
while($row = mysql_fetch_row($result))
{
foreach($row as $cell)
and for ($ColCount = ColCount + 1)
echo "$ColCount", "$cell";
}
mysql_free_result($result);
?>

Answer 1

I have no idea if that's valid in PHP. Maybe all it is is a forgotten $ sign before ColCount. But you could just do it the normal way:
foreach($row as $cell) {
$ColCount++;
echo $ColCount . $cell;
}
$ColCount = 0;

Code:
<!--get artwork thumbnails -->
<?php
$dbname = 'pdartist2';
$table = 'artwork';
// query
$result = mysql_query("SELECT AID, ThumbFilePath, Title, DisplayOrder FROM artwork where SCID = '$SCID' ") or die(mysql_error());
while($row = mysql_fetch_row($result))
{
$colCount = 0;
foreach($row as $cell) {
$colCount++;
echo "$ColCount", "$cell";
}
}
mysql_free_result($result);
?>

As Bruce said, you could just do $ColCount++, But also you could just count the results with mysql_num_rows
$result = mysql_query("SELECT AID, ThumbFilePath, Title, DisplayOrder FROM artwork where SCID = '$SCID' ") or die(mysql_error());
$numRows = mysql_num_rows($result);

You are missing a semi-colon:
<?php $ColCount = 0?>
Should be:
<?php $ColCount = 0; ?>
And:
while($row = mysql_fetch_row($result)) {
foreach($row as $cell) {
$ColCount++; // adds 1 to colcount
echo $ColCount.$cell; // no need for quotes around variables. Also string concatination in PHP is using s dot (.)
}
}
mysql_free_result($result);

What i'll do is use an array like that
<!--get artwork thumbnails -->
<?php
$dbname = 'pdartist2';
$table = 'artwork';
# Define array
$Count = array();
// query
$result = mysql_query('SELECT AID, ThumbFilePath, Title, DisplayOrder FROM artwork where SCID = '.$SCID) or die(mysql_error());
while($row = mysql_fetch_row($result)){
foreach($row as $cell){
$Count[$Cell]['Count'] = $Count[$Cell]['Count']++;
}
echo $ColCount.', '.$cell;
}
mysql_free_result($result);
So you have the count for each colomn but what I suggest is to use the mysql_num_rows(); like that :
$Query = mysql_query...
$Count = mysql_num_rows($Query);
$Count will be a number ;)
Then if($Count > 0)

If you're trying to count the number of columns in each row, then
while($row = mysql_fetch_row($result)) {
$colCount += count($row);
}
though I fail to see point of this. an SQL result set is a perfectly rectangular array. Variable number of rows, but every row will ALWAYS have the same number of fields as all the other rows in the result set. You'd only have to count the columns ONCE and cache that value.
